Interesting question, Jason. I went out in the rain to find my book (in the back of the truck still from our aborted trip to WF last week), and I don't see a P/P listing in 3000 cc. In 2000cc P/P it's 180, in 1650 it's 172, and in1350 it's Rick Yacoucci's 1999 record of 203.392.
I don't see any production classes in the 3,000 cc class. Maybe someone that's cloer to the El Mirage scene will have a better answer.
